## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability polymarket-odds-agentdiet-dev-base-evm-solana-smart-contract-security-ee073343
```

Example prompt: Can you run a security scan on the Base contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and tell me if it has any proxy upgrade patterns or honeypot flags?

## When to prefer this

Choose this endpoint when you need a quick, automated security pre-check on a Base EVM contract or Solana SPL Mint before interacting with it, investing in it, or integrating it into a product. It is especially useful for DeFi agents performing token due diligence, detecting rug-pull mechanisms (proxy upgrades, honeypots), or verifying Solana token freeze authority. Prefer this over generic block explorers when you need a structured, machine-readable security signal rather than raw on-chain data.

## Known failure modes

- Invalid or malformed address returns an error indicating unsupported format
- Contract not deployed on Base or unrecognized Solana mint returns no data or not-found response
- GoPlus API unavailability may result in incomplete honeypot data
- Rate limiting or payment failure (HTTP 402) if x402 USDC payment is not processed
- Very new contracts with no on-chain history may return limited security data

## How this service works

Audits any Base EVM 0x contract or Solana SPL Mint for proxy patterns, GoPlus honeypot flags, and freeze authority. (Live x402 v2, IETF MPP & MCP endpoint at https://polymarket-odds.agentdiet.dev/v1/proxy-upgrade-risk)

## Output

Returns a structured security report for the submitted contract or mint address, including whether the contract implements a proxy/upgradeable pattern, any honeypot flags sourced from GoPlus, freeze authority status for Solana SPL mints, and an overall upgrade/rug risk assessment.
